Hi,
I've lost almost one day on figuring out what follows, so I've just registered to the forum to share and possibly help others. Here is the full story...
I own a LG LW570G TV and successfully tried Plex on Linux (Fedora) few weeks ago. Recently I've updated the LG software / firmware (now running 05.11.08 fw), then retried using the PMS I previously configured on my Fedora box and the LG TV could not found the media server anymore.
I've been doing a lot of tests and finally noticed that *completely* disabling the firewall was "solving" my issue... So, I had a look at connections being established between the TV and PC when the firewall was off and noticed something interesting.
You probably know there's a RedHat related README in the plexmediaserver folder and it says that UDP port 32400 needs a rule to be added in iptables.
Well, I don't know for sure if it's only for the last versions of LG software / firmware, but there's need for few additional rules in iptables; basically the 32410, 32413, 32414 and 32469 UDP ports need the same rule the readme suggests for 32400. This is the rule set that's working for me:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 32400 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 32400 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 32410 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 32413 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 32414 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 32469 -j ACCEPT
-A INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT
-A OUTPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT

Cheers
